Abstract: IMPROVED WICK-TYPE SLOW DIFFUSION DISPENSER    Donald B. Compton William P. Lewis Toan Trinh ABSTRACT An improved liquid material dispenser of the type which transmits fluid to be diffused from an enclosed reser-voir to an exposed evaporative surface by means of a wick. A wick is provided in the form of a sheet which has a very high evaporative area compared to the volume of liquid which is retained outside the confines of the reservoir at a given time.  The critical relation of evaporation area to volume of liquid outside the reservoir is such that the exposed liquid material weight per square centimeter of evaporative surface is less than 10 milligrams per square centimeter. The material to be dispensed, preferably a perfume, com-prises at least 50% of materials of no more than moderate volatility as defined herein.  Materials having low volatil-ity as defined herein are minimized, and the quantity of low volatility ingredients in said liquid materials is related herein to the holding capacity of the evaporative surface of the wick.  The combination of the improved dispenser and improved liquid materials to be diffused maintains the evaporating liquid material at a relatively constant compo-osition, and the liquid material evaporates at a relatively steady rate over the life of the dispenser.

Abstract: ABSTRACT           A hub construction for a torsional vibration damper.  The hub is formed of aluminum to obtain the known damper performance advantages of a lower moment of inertia.  The hub is coated with a Teflon anodized layer to (1) protect it from oxidation, to (2) prevent the formation of aluminum oxide particles at the elastomer-hub interface.  The coating is of a surface roughness of 60 - 70 micro inches, being a roughness in excess of that recommended by seal manufacturers. Unexpectedly, the coating does not injure a seal used with the damper, thus yielding a third advantage.

Abstract: ABSTRACT   The fishing leader holder of this invention consists of an outer cylindrical tube, an inner cylindrical tube rotatably mounted inside the outer tube, a longitudinal slot in each tube which can be mutually aligned, and a cylindrical inner securement part which can slide within the inner tube.  The securement part has a radially extending projection which passes through the slots in the two tubes and, therefore, the securement part can slide longitudinally along the inner tube when the slots are mutually aligned.  At one end of the slot in the outer tube, there is a short slot at right angles to the longitudinal slot so that when the securement part is at this one end of the slot, the inner tube can be rotated within the outer tube to both hold the securement part at one position and to cover the slot in the inner tube. A cap is fitted over the end of the inner tube which is adjacent to the short slot in the outer tube, and a resilient part is secured to the side of the cap facing the inside of the inner tube so that the securement part will be under the effect of the resilient part when its projection is within the short slot, so holding the securement part and the two tubes in their relative positions.

Abstract: ABSTRACT     The invention relates to improvements in air seeders, namely agricultural implements which utilize air pressure to move particulate material such as seeds from a feed zone to a dispersal or planting zone.  The particulate material is normally fed from a hopper by a driven feed wheel or other similar mechanism.  The invention provides a pressure pick-up at the source of air pressure, a conduit connecting the pick-up with a pneumatic actuator and a suitable linkage connecting the actuator with a clutch which is used to transmit drive power to the feed wheel.  As long as there is sufficient pressure at the source the actuator will keep the clutch positioned to permit the feed wheel to operate.  Should the pressure source fail the actuator will operate the clutch to stop transmitting power to the feed wheel and thus terminate the feeding of material which would otherwise clog the delivery conduits of the seeder.

Abstract: ABSTRACT OF THE INVENTION An arrangement for mounting an exchangable disk pack.  The disk pack's hub includes an open ended stub with two retractable steel balls mounted adjacent the open end.  The disk drive's spindle has a coaxial recess for receiving the stub.  The recess has an interior annular groove adapted for registration with the balls.  The stub is inserted into the recess when mounting the disk pack.  When the hub and spindle are in abutment, the balls are positioned just anterior to the annular groove.  The stub is mounted on a diaphragm mounted on the hub.  Depression of the diaphragm moves the balls into registration with the annular groove.  The balls then move from their retracted condition and into the groove under pressure from a push rod moveably mounted in the spindle recess.  After the balls have been pushed aside, the push rod pops up between them and prevents their retraction from the annular groove.  The lodging of the balls in the annular groove prevents the stub from being withdrawn from the recess.          Disconnection is provided by withdrawing the push rod from between the balls;  This allows the balls to retract from the annular groove and the stub to be withdrawn from the spindle's recess.
